feedback control loop

A closed transmission path (loop) that includes an active transducer and consists of a forward path, a feedback path, and one or more mixing points arranged to maintain a prescribed relationship between the loop input and output signals. See feedback (iii).

However, in Systems where Operators must diagnose the root cause of the fault to compensate effectively, then the Interface must support analytical redundancy for every element in the System by making all of the signals in the feedback control loop accessible to the Operator: The output signal from each element must be compared with the expected value, given the input signal and a normative model of the element.

Since then, the concept of using existing data to automate feedback control loops has blossomed into a suite of available features that provide extremely practical use with very little engineering intervention.
The decoupling proposed by our model not only supports the separation of the corresponding feedback control loops, but also the separation of the elements within each feedback loop.
